COMPUTER FUNDAMENTALS

Detailed explanation-1: -Architecture. At macOS’s core is a POSIX-compliant operating system built on top of the XNU kernel, with standard Unix facilities available from the command line interface. Apple has released this family of software as a free and open source operating system named Darwin.

Detailed explanation-2: -Mac OS is based on a BSD code base, while Linux is an independent development of a unix-like system. This means that these systems are similar, but not binary compatible.

Detailed explanation-3: -macOS makes use of the BSD codebase and the XNU kernel, and its core set of components is based upon Apple’s open source Darwin operating system. macOS is the basis for some of Apple’s other operating systems, including iPhone OS/iOS, iPadOS, watchOS, and tvOS.

Detailed explanation-4: -macOS is the operating system that powers every Mac. It lets you do things you simply can’t do with other computers. That’s because it’s designed specifically for the hardware it runs on-and vice versa. macOS comes with an entire suite of beautifully designed apps.

Detailed explanation-5: -In 2000, Apple released Darwin, also a Unix system, which became the core of the Mac OS X operating system, later renamed macOS. Unix-like operating systems are widely used in modern servers, workstations, and mobile devices.
